Abstract

A pointing and control device for a computer system includes: a body (9) that can be manoeuvred by a user; and an inertial sensor (12), fixed to the body (9), for supplying first signals (SAX', SAY', SAZ') correlated to the orientation of the body (9) with respect to a gravitational field (G) acting on the inertial sensor (12). The device moreover includes: a magnetometer (11), fixed to the body (9) for supplying second signals (SMX', SMY', SMZ') correlated to the orientation of the body (9) with respect to the Earth's magnetic field (M) acting on the magnetometer (11); and processing modules (17, 18; 317) for determining an orientation (A, X', Y', Z') of the body (9) in an absolute reference system (X, Y, Z; G, P, N), fixed with respect to the Earth's magnetic field (M) and gravitational field (G), on the basis of the first signals (SAX', SAY, SAZ') and second signals (SMX', SMY', SMZ').
